Answer: A. The number 23 is prime, but 36 is composite.
=====================================================
Explanation:
Let's go through the possible answer choices
- A) This is true because 23 only has the factors 1 and 23. So that's why 23 is prime. We can say 36 is composite since 2 is a factor, ie 36 = 2*18.
- B) This is false because 33 is not prime. Note how 33 = 3*11, showing that 3 is a factor of 33.
- C) Similar to B, the statement "21 is prime" is false. Note how 21 = 3*7.
- D) Like the other false statements, 27 is not prime because 27 = 3*9.
The derivative here is what you get when you bring the exponent down as the coefficient (i.e. the 3) and subtract the exponent by 1. In this case, the answer will be 3x^2.
Answer:
a. x = (2 -3y)/(y+3)
b. x = -4/5
Step-by-step explanation:
<h3>a.</h3>
Clear the fraction, collect x terms, divide by the coefficient of x.

__
<h3>b.</h3>
Put 2 where y is and do the arithmetic.
x = (2 -3(2))/(2 +3) = (2 -6)/5
x = -4/5
Answer:
1509
Step-by-step explanation:
We know that, formula for number of samples is,

When nothing is given, we take
and we know that
.
SE = 0.03 (the true proportion should remain withing 3%)
Putting the values we get,


Therefore, the sample required to estimate the true proportion to within 3 percentage points is 1509.
This is true.only parallelograms have diagonals that both bisect each other.
